Checksums
ITK 5.0.1 is the first patch release that addresses issues identified in the major 5.0.0 release. For more details on ITK 5, see the ITK 5.0.0 Release Notes.
This release improves support for ITK’s use in Dask, the scientific Python distributed computing library, addresses a number of build and runtime corner cases, and makes updates to the Software Guide for ITK 5. For more details, see the Changelog below. Thank you to everyone who contributed to the release.
What’s Next
Join us in the creation of advanced, open source scientific image analysis tools. The ITK Examples are currently undergoing a major integration and update effort lead by community member Hans Johnson – your participation is welcome. Take part in the community discussion at discourse.itk.org. Contribute with pull requests, code reviews, and issue discussions in our GitHub Organization.
We have a soft commitment to backwards compatibility to address any potential API or architectural issues until the next feature release. Stay tuned for upcoming announcements on ITK’s integration with modern web technologies and improved support for Remote Module development on GitHub.
Enjoy ITK!
